Some additional information. After a couple of minutes the session wil disconnect with a message. Here is the rest of /var/log/messages

So after about 30 minutes the session is not be able to be used and a couple of minutes later it will be disconnected by Guacamole. For us we need the SSH-session to be active till we disconnect it ourselves (or maybe after several hours of inactivity). -- Met vriendelijke groet / with kind regards, Mark van den Boogaard Linux specialist [cid:1486709720.5477.39.camel@davantigroup.com] Mob: +31 6 82241436 E-Mail: mark.van.den.booga...@davantigroup.com<mailto:mark.van.den.booga...@davantigroup.com> Web: www.davantigroup.com<http://www.davantigroup.com> Davanti Warehousing B.V.

We connect to our customers with guacamole via a VPN tunnel. Sometimes we keep the SSH-session open but we don't use it for a while. Often the SSH-session freezes when we want to use it again. Is there some way to keep the SSH-session alive until we logout or until the session timeout kicks in? If we use a SSH-application like Putty or SecureCRT we don't have these issues. -- Met vriendelijke groet / with kind regards, Mark van den Boogaard Linux specialist [cid:1486709720.5477.39.camel@davantigroup.com] Mob: +31 6 82241436 E-Mail: mark.van.den.booga...@davantigroup.com<mailto:mark.van.den.booga...@davantigroup.com> Web: www.davantigroup.com<http://www.davantigroup.com> Davanti Warehousing B.V.
